Contribution of power-to-X to energy generation in Germany
Contribution of power-to-X to energy generation in Germany

Renewable gases or power-to-X are essential to meeting climate protection goals because they provide cost-effective solutions for reducing GHG emissions from vehicles, heat generation devices and power production systems, for storing energy long term or for using the final products as chemical raw materials.

For a long time, the wind power industry had no interest in energy storage, because it was much more lucrative to feed the power generated directly into the public grid. However, the end of the 20 years of guaranteed feed-in payments for the first turbines in Germany is in sight. Because of this, operators and planners, including Reinhard Christiansen, are looking for alternatives.
